Description
High-Performance Intake. The Holley GM LS3/L92 Modular EFI Hi-Ram Intake Manifold is engineered to optimize airflow and fuel delivery for high-output engines. Designed for both naturally aspirated and forced induction applications, it enhances power delivery and throttle response in demanding racing environments. This intake manifold performs best in the 3500 to 8000 RPM range, making it suitable for a variety of high-performance engine builds within the LS3/L92 platform.
Construction and Appearance. Made from cast aluminum, this intake manifold offers a lightweight yet durable solution, featuring a rugged finish suited for race-inspired vehicles. Precision-machined EFI fuel rails support high flow rates and help reduce pressure pulsations. Its modular design accommodates a range of EFI tops and serves as a versatile foundation for custom induction systems.
Installation. Installation requires no drilling, utilizing a standard LS3 molded O-ring flange for straightforward mounting. This design facilitates easier installation for experienced enthusiasts and professional builders without extensive modifications.
Warranty. The manifold comes with a manufacturer’s limited 90-day warranty covering defects in materials and workmanship.
Application. This intake manifold is designed primarily for LS3/L92 style rectangle-port cylinder heads and intended for racing and high-performance use. It supports naturally aspirated and forced induction setups in engines within the LS3/L92 family. While fitment may align with some GM models, specific vehicle compatibility should be verified by the installer based on engine configuration and head style, as it is not intended as a direct bolt-on for all LS variants or specific models without potential modification.
